Frank wanted to see whether adding some compost to the soil would affect the size of the vegetables in his garden. He created two pumpkin patches with similar sun exposure. In one patch, Frank used only the natural soil in his garden, and in the other patch, he mixed some compost in with the natural soil. He then sowed the same type of pumpkin seeds in both patches, and watered them on identical schedules. When the pumpkins were ready to harvest, Frank measured the approximate diameters, in inches, of the pumpkins in each patch. The summary statistics are shown in the table. What is a 90% confidence interval for the difference between the mean diameters of the pumpkins in each patch? (You may assume that there are = 30 degrees of freedom.)
A) (3.83, 8.17)
B) (4.20, 7.80)
C) (4.61, 7.39)
D) (4.73, 7.27)

yes

step-by-step explanation:

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !

a precentage of 6th graders. the population is all 6th graders. let me know if i'm wrong, i hope this ! : )

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
